The Lounge Chair That Has No Welds, No Joints, and No Legs - Just One Bent Sheet of Metal - Yanko Design

Arc One is a lounge chair that keeps sheet metal fully visible instead of hiding it as an internal skeleton. The chair forms a continuous side profile where the bent metal sweeps from the backrest plane through the seat pan and curls into the base, with no legs or secondary structure.

The single-piece body eliminates welding and mechanical fastening, allowing flat stacking for storage and transport. Leather cushions attach with visible leather straps and snap fasteners, keeping the structural and attachment details prominent.

The bent metal does all of it simultaneously, and Özdemir arrived at that form using only laser cutting and CNC bending, two processes that leave no room for the kind of hand-finishing that usually disguises manufacturing decisions in premium furniture."

"Most lounge chairs are assemblies, a frame joined to a seat shell joined to a base, each junction representing a production step, a potential failure point, and a logistics complication. Arc One eliminates all of that. The single-piece body requires no welding and no mechanical fastening, which means the bare frames stack flat for storage and transport, a logistical advantage that most furniture at this aesthetic level completely ignores."

"A round tufted back cushion and a square tufted seat cushion attach to the metal body via leather straps with snap fasteners, hardware that belongs more in a saddle shop than a furniture atelier. The strap details are visible and intentional, running h"
